The Big Island of Hawai'i is composed of five volcanoes... Kohala, Mauna Kea, Hualālai, Mauna Loa, and Kilauea.

Hualālai and Mauna Loa are expected to erupt again. Mauna Kea can still be active though there are no current indications. The current active volcano is Kilauea which has been spewing forth lava pretty much nonstop since it began - and is among the worlds most active volcanoes.

Currently lava comes out at the Pu'u 'O'o vent inside the Hawai'i Volcanoes National Park. Depending on conditions the lava is quite often accessible and offers visitors an experience of a lifetime.

Lava flowing from Pu'u 'O'o normally flows through lava tubes towards the ocean 6 miles away. About two miles before the ocean the lava encounters a 1,200 foot cliff which is flows over, and then two to three miles of coastal flats until it pours into the ocean. Often the lava is visible on the Pali (cliff), on the coastal flats, and at the ocean entry.

In the huge Kilauea Summit caldera itself site Halema'uma'u Crater. On March 19, 2008, a vent opened in the crater causing a portion of Crater Rim Drive to be closed. The vent is still open but lava continues to remain below the surface of the vent.

We have much to say about the volcano and the lava - this page lays out the various sections that you can visit.

Activity Summary: Kīlauea Volcano is not erupting. Rates of seismicity, deformation, and gas release have not changed significantly over the past week. Deformation signals are consistent with refilling of the middle East Rift Zone.

Observations: HVO monitoring during the past week shows low rates of seismicity at the summit and East Rift Zone (ERZ). Earthquakes continue to occur primarily at Kīlauea's summit area and south flank, with continued small aftershocks of the magnitude-6.9 quake on May 4, 2018. Seismicity remains low in the lower ERZ.

In the ERZ, tiltmeters near Puʻu ʻŌʻō and farther east reveal no change over the last week. At the summit, tiltmeters have also shown little change this week, with the exception of a small DI (deflation-inflation) event.

Sulfur dioxide gas emissions at the summit averaged 50 tonnes/day as reported on October 24, and 75 tonnes/day at Puʻu ʻŌʻō on October 23. There was no sulfur dioxide detected by our instruments in the lower ERZ.

Hazards are still present in the lower East Rift Zone (LERZ) eruption area and at the Kīlauea summit. Residents and visitors near recently active fissures and lava flows should stay informed, heed Hawaii County Civil Defense and National Park warnings, and be prepared, if necessary, to self-evacuate in the unlikely event of renewed activity. Please note that Hawaii County maintains a closure of the entire flow field and the vents and prohibits access to the area unless authorized through Civil Defense.

The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea's seismicity, deformation, and gas emissions for any sign of reactivation, and maintains visual surveillance of the summit and the East Rift Zone. HVO will continue to issue a weekly update (every Tuesday) and additional messages as warranted by changing activity.
